What feature or improvement would you like to see?

In the recently added search behavior, the driver managers search for manifests and drivers in a directory named adbc (or ADBC). But in the future, it's foreseeable that we might want to add other types of ADBC-related configs in this location (in addition to drivers and their manifests). In anticipation of this, could we please add a subdirectory there named drivers (or Drivers) and have that be where the driver managers search for manifests and drivers? This might seem like an unnecessary level of nesting for now, but in the future it will make adding more ADBC configs here much cleaner.

Note that this is already what we're doing for the registry keys on Windows.
